Year 1

Describe ways of solving puzzles and problems, explaining choices and decisions orally or using pictures

Count reliably at least 20 objects, recognising that the number of objects stays the same when rearranged; estimate a number of objects that can be checked by counting

Compare and order numbers, using the related vocabulary; use the equals (=) sign

Read and write numerals from 0 to 20, and then beyond; use knowledge of place value to position these numbers on a number track and number line

Say the number that is one more or less than any given number, and ten more or less for multiples of one.

Relate addition to counting on; recognise that addition can be done in any order; use practical and informal written methods to support the addition of a one-digit number or a multiple of ten to a one-digit or two-digit number

Understand subtraction as 'take away' and find a 'difference' by counting up; use practical and informal written methods to support the subtraction of a one-digit number from a one-digit or two-digit number and a multiple of ten from a two-digit number

Use the vocabulary related to addition and subtraction and symbols to describe and record addition and subtraction number sentences
